Using the STS16-20 Chassis View NOTE The Port Status options allow you to display status information for the 20 built-in Token Ring ports. The Port Status options do not display status information for any SSIMs installed in the STS16-20RM and STS16-20FRM. To change the port status display: 1. Click on Port Status in the Chassis View menu bar to access the Port Status menu. 2.
Using the STS16-20 Chassis View NOTE For this release, the Load port status option will display three dashes and maintain the color code of the most recently selected Port Status option for any unlinked ports (i.e. ports for which the Operator status is OFF). Errors Displays the percentage of the total number of valid packets processed by each port during the last polling interval that were error packets.
Using the STS16-20 Chassis View Displaying MIBs and MIB Components Like most networking devices, the STS16-20 draws its functionality from a collection of proprietary MIBs, and IETF RFCs. The MIB data is organized into a series of Òcomponents,Ó which is a logical grouping of MIB data with each group controlling a deÞned set of objects. There is no one-to-one correspondence between MIBs and MIB components. A single MIB component might contain objects from several different proprietary MIBs and RFCs.
